Why do women within western countries enjoy difficult risk getting breast cancer?
Answers: For the most part, it's a mystery - as is the reason that surrounded by many Asian countries (which have a much lower rate of breast cancer) stomach cancer rates are through the roof, much, much higher than rate sin the west.
pular explanation is diet; but in that are no foods proven or suspected to be linked to the development of breast cancer.
A recent popular theory have been that dairy is the cause of breast cancer, and that's why in Japan, for example, breast cancer rates are low. This ignore the fact that there are women in the west who don't consume dairy who still develop breast cancer - I'm one, I be diagnosed with it after many years as a vegan
Also, you may want to consider life expectancy; breast cancer is mainly a disease of ageing and 80% of those diagnosed with it are over 50. The average age at diagnosis is a moment or two over 60.
In countries where life expectancy is 40 or even 30 something years, women will usually not live long enough to develop breast cancer. In, for example, the US and the UK where on earth life expectancy is in the late 70s, the majority of women do live long adequate to be at risk of breast cancer and around one in eight develop it
1) they have a smaller amount babies.
hey start having babies later contained by life.
4) they start having periods precipitate and continue periods later contained by life, sometime with hormones to help hang on to the cycles.
Explanation: This has nothing to do with the breast function itself. It have to do with how many menstrual cycles and hormonal (estrogen/progesterone) exchanges they have. In countries/cultures where on earth women start having babies very young, and they hold a lot of babies, and they breast feed them (further keeping the cycles away), the breast cancer rates are lower. In affluent "assimilated" western cultures, the listed above situation occur and they have a higher breast cancer rate.
